1. (After lot of played pvp matches) I need to mention, that warrior class first skill ("sever") should definitely be modified in range. Since every player in combat runs and jumps around like a crazy, it's a matter of luck to successfully hit with this skill. Range should be at least 180°. This is my first suggestion.
2. About second suggestion Iam not completely sure, but i think that EITHER paladins first skill could be slightly stronger. For example 110% attack power instead of 100. OR holy shield skill duration should last some seconds longer.
3. Final suggestion: Groups in public queue should be limited for 2 members. (Group of 24/7 maniacs against regular players who just want to play for fun, is non-sense)
Let me know if you take my suggestions seriously, maybe then i could make some more.
